“…gagné and Jaschhof (2014), which created a worldwide catalog of cecidomyiids, hypothesize that the number of unidentified Cecidomyiidae species is inestimable, especially in the tropics. Due to the large floristic diversity of Brazilian grasslands, forests and savannas (Forzza et al 2012), Brazilian biomes are likely to harbor 2004, Bergamini et al 2017). Myrtaceae was found to be more important in Atlantic Forest inventories (e.g., Rodrigues et al 2014, Maia and Silva 2016, while Asteraceae was found important in inventories of Atlantic Forest (e.g., Fernandes et al 2001 and Cerrado (Carneiro et al 2009, Coelho et al 2013b).…”

“…Gall-inducing organisms are considered to be the most sophisticated herbivores found in nature [1], given that they are the only herbivores capable of manipulating plant tissues inducing the formation of structures called galls [2][3][4]. Fungi, bacteria, viruses, nematodes, and arthropods are capable of inducing galls in plants, but arthropods are undoubtedly the most diverse and studied galling group [5,6]. The arthropods inducing mechanisms that promote tissue modifications are diverse, ranging from the reaction of plant tissues to the piercing activity of mouthparts, saliva components, hormones released by the female ovipositor at the time of laying eggs, or even substances in the eggshell [4,7].…”

“…The great diversity of gall-inducing taxa shows that the galling life-style evolved repeatedly within and among arthropod groups [7]. Despite the convergence of these taxa to a highly specialized guild of sessile endophytic herbivores, different groups of gall-inducing animals may have different patterns of interaction with their host plants [5,10,19]. Previous studies suggest that plant-galling interactions can vary between distinct galling taxa [19,20] and between galling species within the same taxon [21].…”

Host Specialization in Plant-galling Interactions: Contrasting Mites and Insects

et al. 2019

Galling arthropods represent one of the most specialized herbivore groups. On an evolutionary scale, different taxa of insects and mites have convergently adapted to a galling lifestyle. In this study, we have used a multi-taxonomic approach to analyze the interaction specialization between gall-inducing mites and insects and their host plants in the Nitra City Park (Nitra, Slovakia). We used four ecological descriptors for describe plant-galling interactions: number of host plant species used by each arthropod species, galling specificity on host plant species (specificity), exclusivity of interactions between galling and plant species (specialization) and overlap of the interactions between arthropod species (similarity). We have found 121 species of gall-inducing arthropods, totaling 90 insects and 31 mites occurring on 65 host plant species. Our results reveal that mites have high specialization and low similarity of interactions in comparison to insects. A multiple-taxonomic comparison showed that these differences are triggered by gall-wasps (Hymenoptera: Cynipidae), the taxon with the lowest levels of specificity of plant-galling interactions (i.e., occurring on different host plant species). Our findings are indicative of different patterns of interaction between distinct gall-inducing arthropods taxa and their host plants, despite the ecological convergence of different taxa to a highly specialized herbivorous habitat.

“…Despite this, some of its phytophysiognomies have been little studied, as is the case of gallery forests. Studies of gall richness in gallery forests have been rare in Brazil, and they were initiated only in the early 2000s (Urso-Guimarães et al 2003;Araújo et al 2011;Luz et al 2012;Bergamini et al 2017). That situation is no different in gallery forests in Northeastern Brazil; only one study has yet been undertaken in Bahia (Silva et al 2018).…”

Insect galls and their host plants in gallery forest in Bahia State, Brazil

et al. 2020

Inventories of insect galls in gallery forests in Northeastern Brazil have been quite infrequent, and the richness of gallinducing insects in that vegetation type has been little unknown. To contribute to our knowledge of galls, galling insects, and their host plants from gallery forest habitats in Northeastern Brazil, we documented and characterized the macroscopic aspects of the galls, identified the plant hosts and their endemism level and surveyed the associated fauna in an area of gallery forest in Caetité, Bahia State. We found 30 different gall morphotypes on 20 host plant species belonging to 17 genera and 13 families. The main host families of galls were Leguminosae and Myrtaceae with ten and four morphotypes, respectively. Most galls occurred on leaves and were globoid, green, glabrous, and grouped. Most of the gall-inducing insect species found belonged to Diptera (Cecidomyiidae) and Coleoptera, while the associated fauna was represented by Hemiptera, Hymenoptera, Collembola, and Thysanoptera. We recorded galls the first time on six plant species. These results reinforce the importance of gall inventories in gallery forest areas not yet examined to better understand gall richness, galling insects, and their host plants in that vegetation type.
